On midair collisions
 

When I learned to fly there was a saying about midair collisions"It'll spoil
your day". Several years later I had a close call I won't forget, I was flying in
the North End of YUL controlled airspace on a hasy summer afternoon
I crosed under the nose of what I beleive was an HS748, I called ATC
and ask to confirm they had me on radar after a long pause there
was an affirmative reply, which was enough the make my point my day
was saved.Beware!!!! From the great white North
